IMPROVEMENT IN MARKERS FOR CORNF-PLANTERS.

Specification forming part of Letters Patent No. 177,293, dated May 9, 1876; application filed March 8, 1876.

To whom it may concern:

Be it known that I, CHARLES W. SPEAK, of Braddyvjlle, county of Page, and State of Iowa, have invented certain new and useful Improvements in Markers for Corn-Planters,

provements in devices for attaching to cornplanters for the purpose of making a mark in the soil to indicate proper position for the furrow-openers at the next passage of the machine; and the invention consists in the use of an extended bar,oarrying markers on each end, and which takes the place of and operates as the double-tree, havin g the sin gle-trees attached thereto. One end of the marker or both ends may also be hinged, so that it may be turned upward when desired, all as hereinafter fully described.

Referring to the parts by letters, letter A represents the forward, and B the rear, part 01 an ordinary corn-planter, the fore part of which is hinged to the rear part, and carries the usual tongue or draft-pole O. D is a bar extending from the tongue 0 in each lateral direction adistance beyond each furrow-opener The nature of my invention relates to imequal to the distance between the furrow-openers. The bar D is mounted on the tongue 0 in the usual place for the double-tree, and has the single-trees 61 attached to its front side.

E E are the drags for making the marks, E beingaweight attached, by a chain, c, to the bar D, and E being a runner-shaped plate, attached directly to the bar D. G is a hinge in one end of the bar D, and permits turning the end of the bar D upward, as shown by dotted lines at Fig. 2. Both ends of the bar D being extended prevents side draft, and the neces sity, incident to a single extension, of having to readjust and turn it at the ends of every row. The single-trees being attached to said bar dispenses with the double-tree. The joint G permits'turning the end'of the bar D upward for the purpose of facilitating passage through gates and other narrow places.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- Y 1. The dually-extendedbar D, having marking devices on its ends, and pivoted to the draft-pole 0, so as to operate as a double-tree, substantially as set forth.

2. In a land-marker, the combination of the draftpole O with the pivoted bar D, having the single-trees d, and extended hinged ends provided with marking .devices, substantially as and for the purpose set forth.
